Draft Statement of Work
1.
OVERVIEW / BACKGROUND. The Library of Congress (Library) requires contract support to acquire a temperature and humidity controlled chamber for use in its quality assurance program for the testing of papers, boards, etc. against multiple ISO standards in addition to ongoing research on materials degradation in relation to the Library’s collections. Testing the physical and chemical properties of materials, and how they change during aging, is central to the Library’s quality assurance testing program for materials used in the storage and housing of collections and ongoing research programs. Many of the specifications rely on published ISO testing standards such that specific capabilities of testing equipment are required as they are specified in the international standards (ISOs) that have been used to develop the Library’s specifications. 2.
SCOPE This contract will acquire a temperature and humidity controlled chamber for use in the Library’s quality assurance program for the testing of papers, boards, etc. to multiple ISO standards in addition to ongoing research on materials degradation in relation to the Library’s collections. The contract should include all parts and equipment to meet specified parameters, user training, shipping, and 1 year of warranty support.
